Area Forecast Discussion National Weather Service Honolulu HI 954 AM HST Wed Aug 5 2020

SYNOPSIS. A strong surface high will remain north of the islands through at least early next week. Breezy easterly trade winds will focus showers over mainly windward areas, with afternoon showers over the leeward side of the Big Island of Hawaii. An area of moisture moving west over the islands may make showers more active tonight through Friday.

DISCUSSION. As of 8 AM, the surface analysis shows a 1031 mb high centered about 1080 miles north of Honolulu near 37N 155W. The high will maintain locally breezy easterly trade winds over the main Hawaiian islands as it moves slowly northeast and strengthens through early next week. Satellite loops show mostly cloudy skies over windward areas and mostly sunny skies over leeward areas with clear skies over the high elevations of the Big Island and Maui. Radars show isolated showers moving toward the islands in the trade-wind flow. Clouds and showers will develop over the lee slopes of the Big Island and Maui this afternoon, otherwise little change is expected through this evening.

An area of more-humid air is forecast to move west across the islands through Friday. This will likely produce an increase in windward showers tonight through Friday morning. Some of these showers may spread leeward over the smaller islands, mainly during the night and morning hours. The increased moisture may also fuel an increase in afternoon showers over the lee slopes of the Big Island and Maui through Friday.

Over the weekend, drier air will spread over the islands from the east. Trade winds will strengthen over the weekend and could get strong enough to require issuance of Wind Advisories.

AVIATION. High pressure north of Hawaii will help to maintain moderate to breezy trade wind flow through this evening. An area of enhanced moisture upstream is forecast to move over the area from the east later today and into tonight. This will bring scattered to numerous showers to the windward sections of the islands with MVFR ceilings and visibility likely. Isolated to scattered showers elsewhere.

AIRMET TANGO remains in effect below 8000 feet for areas over and immediately south through west of mountains.

MARINE. Strong high pressure far north north of the area will remain nearly stationary maintaining locally strong trade winds over the area. A Small Craft Advisory (SCA) continues for the windier areas near Maui County and the Big Island into this weekend. Winds could increase this weekend that would extend the SCA for the existing areas, and could require the SCA to be expanded to additional waters.

A small, and fairly short-period, southeast swell will persist into next week but the Big Island will block some of this swell from reaching the rest of the islands. Long-period swells from deep in the southern hemisphere will remain small, but help to keep surf along the south shores elevated. Small surf along east facing shores will build through the weekend as trade winds strengthen.

HFO WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory until 6 PM Saturday for Maalaea Bay, the Pailolo and Alenuihaha Channels and waters south of the Big Island.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
